Reddit user Rachel got a big surprise when she opened gifts sent to her by an internet Secret Santa. Reddit’s annual gift exchange had sent her name to none other than Microsoft founder Bill Gates.

Buzzfeed reports that Rachel didn’t really know who “Bill” was at first, but he seemed like a nice guy. His gift to her was a donation to Heifer International. Here is what his card to her read:

To Rachel,My Secret Santa present to you is a cow!Don’t worry – you will not have to build a barn. This cow will be given to a family in need, in your name, through Heifer International. It will provide them with income and dairy products, and it will help them help themselves.Happy Holidays,Bill Gates
